Palm kernel shells (PKS): are the hard, woody endocarps of the oil palm fruit, left as a byproduct after the extraction of palm kernel oil. Once considered agricultural waste, PKS is now a high-demand, sustainable biomass fuel and industrial raw material.
Physical & Chemical Characteristics
Appearance: Small, irregularly curved, brownish-yellow to black fragments with a hard, fibrous texture.
Energy Content: High calorific value ranging from 15 to 19 GJ/MT (approx. 3,800 to 4,500 kcal/kg). low ash/sulfur content, and consistent supply, making them an excellent sustainable alternative to coal or wood chips for industrial power plants and boilers
Composition: High in lignin (approx. 50-54%) and carbon (approx. 45-50%), contributing to its high energy density and structural strength.
Moisture & Ash: Typically contains 10-15% moisture and very low ash content (approx. 3.5%), making it a cleaner-burning alternative to coal.
Density: Exhibits a high bulk density of about 520-620 kg/m�³, which reduces hauling costs compared to other biomass.
Its hard, porous structure makes it an ideal precursor for high-grade activated carbon used in water purification, gold recovery, and air filtration.
Industrial Additive: Used as an abrasive for industrial cleaning, a lightweight filler in road construction, and a reinforcement material in bio-composites.
Agriculture: Applied as a soil conditioner or mulch to improve aeration and water retention.
Technical specifications for Palm Kernel Shells (PKS) vary depending on whether they are in their Raw (biomass) state or have been Carbonized (charcoal).
Raw Palm Kernel Shells (Biomass Fuel)
PKS is primarily graded by its energy content and moisture levels for use in industrial boilers.
